Part Number: TAS5508C
We planned to use audio PWM Processor TAS5508C in our new project, We need to implement 8 channel ADC wIth TAS5508C.
The current concept is four PCM1808 used as the input channels. But we have some doubts in its clock connectivity, how to interface its multiple clocks(From four PCM1808) with TAS5508C?
Do we need to add any additional device in between both devices?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thanks for your response!
When we connect the both device(TAS5508 & PCM1808), which one will be working as master? As mentioned in the datasheet TAS5508C is a clocked slave-only device.
The TAS5508C receives MCLK, SCLK, and LRCLK from other system components. So we need any additional master device?
We found 8-Channel A/D Converters CS5368 from cirrus logic, is this possible to work with TAS5508. The ADC will generate the clock for TAS5508.
Can you suggest any alternative part of A/D Converters (like PCM1808, CS5368 )compatible with the TAS5508 spec?
The project currently in architecture stage.
In reply to jom sabu:
My mistake, one of the four PCM devices should be configured as a master, the other three PCM and the TAS5508 should be slave. Use a crystal as a master clock into the master PCM1808 device. Then all other PCM1808s and TAS5508C will be slaves taking the SCLK from the crystal and BCK and LRCK from the master PCM1808 device.
There is no need for a CS5368.
Thanks for your valuable information!
Is it possible to connect single crystal for entire system clock SCKI (4-PCM1808 and TAS5508 )?
